To all LlilL-O'II'L Lt may 0011mm:-

Be it known that I, Wanroan L. McCAarr,

a citizen of the United States, residing at Memphis, in the county ofShelby and State of Tennessee, have invented a new and useful PrintingDevice, (Case B,) of which the following is a specification.

This invention relates to printing devices, and hasspecial reference toa device adapted to be used to repeatedly print the same arrangement ofcharacters or words on a con tinuous web.

One object of the device is to provide an improved general constructionof such mechamsm.

Another object of the invention is to pro vide an improved form ofcontact between the printing roller and the web to be imprinted.

The invention consists in general in a web actuating printing mechanismincluding a platen of a cylindrical form having type thereon, an in ringroller for said form together with certain im rovements in the supportfor the inking r ler.

e invention further consists in certain novel details of arrangement andcombination of arts hereinafter fully described, illustrated in theaccompan ing drawings, and specifically set forth in t 1e claims.

' In the accompanying drawings like characters of reference indicatelike arts in the several views, and Figure 1 is a ongitudinal sectionthrough the device. Fig. 2 is a transverse section on the line A-A ofFig. 1. Fig. 3 is a perspective view of the bottom portion of the webroll support. Fig. 4 shows a modified form of spring for pressing theprinting roller against the inking roller and p laten. Fig. 5 is adetail perspective view of the loose-jointed frame used in con nectionwith this invention.

The device is contained within a casing which is provided with asuitable cover 11 having erforations therein adapted to register withsimilar perforations in the easing 10 and receive a headed rod 12 havingan eye at the small end to receive a lock 13. The casing is furtherprovided with an opening 14 adapted to receive a web 15 and an exitopening 16 for said web. At one end of the casing there is provided aplurality of slots 17 having enlarged ortions 18.

Standards 19 having s otted upper ends, as indicated at 20, are spacedapart and re- 1 ceive a rod 21 whereon is mounted a web roll 22. In theslot above the web roll is a headed bar 23. This bar fits loosely in theslot 20 and at all times presses firmly against the web roll 22 so thatit forms'a tensioning device therefor. Below the web roll 22 is mountedan arm 24 whereon is supported a web-guiding tube 25. Adjacent. thelower end of the tube .25 is a roller 26, this roller being mounted atthe bottom of the web roll supports 19. The web roll suports areprovided with headed lugs 27 having flattened portions 28. The heads 27are somewhat smaller than the enlarged 0 enings 18, but larger than thelower on s of said openings, as at 17. These lugs are disposed on thebottom of the standards in commensurate relation to the slotted openings17 and the length ohthc lugs is such that when the heads 27 are insertedin the openings 18 and pushed down to the reduced portion 17, theseheads will closely engage the inner side of the casing and thus lock thestandards. 19 firmly against the same.

Mounted in suitable bearings within the casing is an inking roller 29provided with a fixedly attached gear 30. Adjacent this inking roller isa roller platen 31 provided with a similar gear 32, the platen beingmounted for rotation in suitable bearings on the casing. Beneath theinking roller and platen is a tensioning roll 33 provided with a gearrigidly attached thereto, as at 34. The gear 34 meshes with the gears 32and 30. The web 15 passing down through the tube and under the roller26, enters the casing through the opening 14, passes under the roller 33over t 1e platen 31 and out through the opening 16. The platen 31 androller 32 are so arran ed as t'o-dianieter and gear ratio, that the r0ler 33 revolves ata lower rate of speed than the platen 31. The web 15is thus con stantly tensioned so that it will lie snugly against theplaten 31. Beneath the-inking roller 29 is a drip pan 35 adapted toreceive any surplus of ink that may escape from said roller.

A frame 36 is pivoted to the casing, as at 37. The pivotal connection37is so arranged that the pivot pin is of slightly smaller diameter thanthe hole through which it asses. and the space between the head of t 1epin and the casing is slightly greater than the thickness of the framesides. The frame sides are extended upward, as at 38, and

1 ranged to receive suitable type characters.

these extensions are connected by a rod 39 loosely mounted therein.

served that by means of the looseness of the various parts one end ofthe frame may be 7 moved without affecting the other. At the j outer endof the frame each of the sides is provided with a slot 40 extending.downward 5 from the end of the frame and angled up- 3 ward, as at 41.The portion 41 of this slot 5 forms bearings for a printing roller 42ar- This roller 42 is positioned to contact with the inking roll 29 andthe web 15 as it is drawn over the platen. Mounted on the rod 39 is aweight 43, and arms 44 having screw- I threaded ends are attached to thesides of the frame 36. Upon the upper end of these 1 arms, and bearingagainst the casing cover y when the same is closed, is a rubber or otheri spring 45. i

, It will now be plain that any inequality in either the inking rolleror the platen 31 will i be met by the yieldable loose frame 1nountingfor the roller 42 and that this roller will I be kept constantly andfirmly in contact both with the inking roller and the platen or webthereon without regard to the inequality of g the surface orirregularity of movement. I

In the form shown in Fig. 4 the spring ,30 .45 of Fig. 1 is replacedwith a spring 46 attached to the loose-jointed frame and the a bottom ofthe casing, so that it acts in a man- I ner precisely similar to thespring of the preferred construction.

In the operation of this device the Web is drawn'through the printingmechanism by any suitable means, as by that shown in the patent to inc,the application of which bears Serial No. 397,926, and which was filedOctober, 17, 1907. This causes rotation of the platen 31 by reason ofthe friction of the web thereon, and thus in turn rotates the inking iit is not desired therefore to confine the in. vention to toeexactform'lmrcin shown and rotation of the inking roller combine torotate the printing roller and there is thus impressed on the Web arepeated series of the characters or words of the type held on theinking roller.

It is obvious that changes may be made in the form and proportions ofthis device withroller. The-movement of the web and the I out departingfrom the principle thereof, and

described, but it is wished to include all such that properly comewithin the scope. of the invention. a
